SF Gate: Grateful Dead members keep rocking — with John Mayer

Devoted Deadheads may never get over getting duped by their favorite band, who claimed to be bidding adieu forever after the 50th anniversary concerts at Chicago’s Soldier Field, only to have three of the band’s four surviving members — Mickey Hart, Bill Kreutzmann and Bob Weir — reconvene weeks later for a tour with guitarist John Mayer. Yet here they are, playing the old favorites with renewed vigor and closing out the year with a promise of more to come.

Dead and Company: 8 p.m. Sunday-Monday, Dec. 27-28. $75. Bill Graham Civic Auditorium, 99 Grove St., S.F.www.ticketmaster.com.
